Well if you have other plants that are experiencing none of these symptoms and are under the exact same parameters you have two options:
Damaged roots
Runt, kill it and put a different plant in its place.
Like others have said and I have learned the hard way I gave up trying to rescue plants if they are that young and are having that many issues I know by day seven or eight if I’m going to even keep the plant.
Hopefully your other plants will continue to thrive sometimes we just hit speed bumps!
Edit - looking at the very first picture in your thread and looking past the picture of the plant in question that other plant in the back corner is not healthy it is experiencing the exact same parameters as the one that you were requesting status help with.
So it is not that the plant is a runt the fact is the plants are all damaged because something’s wrong and I would bet pH with nutrient lock out.
The plant in the back was dwarfed by my previous light… I have 1 other one that is the same way, I’m seeing if they’ll come around, but I losing hope by the hour.
If you broke the tap root the plant would be wilting for sure.
I just did it accidentally a week ago on a clone, and I’ve done it numerous times replanting from hydro.
The top clone is the one I damaged. You can see how it started to wilt within hours. I had to prop it up or it would’ve been totally flopped over wilting.
For those asking (@nefrella, @George, @Hidden, @Slammedsonoma420, @shag), in aquaponic systems, where fish waste contributes to nutrient availability, the presence of beneficial bacteria helps convert fish waste into forms usable by plants. These bacteria thrive in slightly alkaline conditions, which can result in a pH range of 6.8-7 being suitable for marijuana plants.
In hydroponic systems, where plants rely solely on nutrient solutions provided by the grower, the pH requirements can be different. Lower pH levels, typically below 6, are often preferred in hydroponics because it helps to ensure better nutrient availability to the plants, especially for certain minerals like iron and manganese, which can become less available at higher pH levels. Lower pH in hydroponics can also reduce the risk of nutrient deficiencies and potential nutrient lockout.
So, while marijuana plants can tolerate slightly higher pH levels in aquaponics due to the microbial activity and nutrient cycling from fish waste, hydroponic systems require lower pH levels to optimize nutrient uptake directly from the nutrient solution.
Indeed it is an interesting subject, but it might be difficult to find the correct balance, too much nitrates may kill the plants. Here in Spain we have a minor sea whose plants and algae are suffocating and dying because of all the nitrates that comes from the fertilized crops that surround and rivers that takes them to the sea.
Found this interesting read, there is always something new to learn …
7.2 vs 6.5 vs 5.8 aren’t slight differences. +/- 2-3 tenths are slight differences but getting near the borderline of too much. Some strains won’t even tolerate that much without hermieing. The whole survive vs thrive ordeal.
Looking good is subjective. The ideal nuetral target of 6.8-7.2 for a balanced aquaponic system isn’t favorable to acidic plants, it’s just how life is. Transplanting into straight hydroton is obviously going to be very rough on the roots and will continue to damage them anytime they shift due to the weight and abrasiveness until the root mass takes over. That plant was already showing stress before the move.
It’s possible the hydroton hasn’t yet been populated with all the beneficial enzymes and bacteria the plant needs to feed it and since it can’t feed itself due to the high ph, its recovery is being hindered. And that once it does get fully populated within the hydroton and root system with the required bacteria it will return to the “looking good” state in the photo.
The question becomes, will the plant survive long enough for the bacteria to save it? Or are you willing to employ alternative methods? If it was I plant I thought was worth saving, I’d chuck the whole bag in a hempy bucket, flush it a few times, buffer ph to 6 and give it a handful of osmocote.
Hey not sure your location but there’s an Ohio based company called rid-all that grows TONS using aquaponics. I know you know what you’re doing but they are wildly friendly and would probably answer questions or offer advice if needed.
I should reiterate, “good” for that plant is relative… It’s the only one that didn’t become dwarfed, so it’s had a hard start and was coming out of it really well.
I did a big flush on it yesterday and trimmed off the dead leaves and it looks to have a little life today. @Hidden, you nailed it with the new clay not being populated yet, I’ve also dumped a bunch of water over it now to try and helped with that.
Thanks all… I’m not holding out a ton of hope, I’ve already started a couple replacement seeds, but I figure if it takes off I’ll just move her to the grow bed the bags are all sitting on and see how it goes
